RADIATOR Filed 00f. '23. 1930 Patented May 9, I933 v UNITED STATESEDMUND ROSER, F BOCHUM, GERMANY RADIATOR Application filed October 23,1930, Serial No.

My invention relatesvto improvements in radiators and more particularlyin radiators provided with a fan for circulating the air and rapidlydelivering the same into the room to be heated. The object of theimprovements is to provide a radiator of this type in which the heat israpidly and thoroughly transmitted from the radiator elements and theheating effect of the radiator is improved. Another object of theimprovements is to provide a radiator in which excessive heating ofcertain parts of the radiator is avoided. With these objects in view myinvention consists in disposing the fan at the rear side of the radiatorcomprising a plurality of heating elements disposed one beside the otheror one above the other, the fan being disposed so that the air rises atthe rear side of the radiator, where- 0 upon it is deflected at its topfor flowing downwardly along the front side of the heating elements.Thusthe air is delivered from the radiator in a direction towards thefloor of the room and at a part of the radiator where transmission ofheat also takes place by radiation.

In one embodiment of the invention I make use' of electrical heatingmembers mounted on rods of insulating material, the

said rods being individually disposed within semi-cylindrical screensdisposed one above the other or one besidethe other and overlapping oneanother with their longitudinal margins and providing slots at the 3said margins for the passage of the air therethrough. Thus a part of thecurrent of air flows from the rear side of the radiator to the frontthereof, and it is directed against the electrical heating elements.Thus when switching in the current the room is 'rapidly heated becausethe heat cannot be stored at any part of the radiator, and it isdirectly transmitted by the current of air and by radiation into theroom. By the current of 5 air also the cold air located near the flooris moved and replaced by warm air.

For the purpose of explaining the invention twoexamples embodying thesame have been shown in the accompanying drawing in which the samereference characters have 490,695, and in Germany October 25, 1929.

been used in all the views to indicate corresponding parts. In saiddrawing,

Fig. 3 is a sectional elevation showing a modification,

Fig. I is a sectional elevation taken on the line 4:-4 of Fig. 3, and tIiig. 5 is a sectional view showing a de- In the example shown in Figs.1 and 2 the radiator is heated by means of gas, and it comprises upperand lower tubular members 10 and 70 connected by vertical pipes b, thegas being supplied through a pipe Z and the burned gas escaping througha pipe Z The radiator is supported on a base m, and it is confinedwithin a casing comprising a rear wall 0 and a front wall 6, the saidwalls be ng connected at their top by a semi-cylindrical wall having acontainer z for water fitted therein. The casing c, e is divided by theradiator and partition walls n located between the pipes b and extendingto the side walls of the casing into a rear chamber a and a frontchamber a and the rear chamber a is closed at its bottom by a plate M.The rear wall a is formed with a circular hole having a flanged ring afitted therein, and to the rear wall a frame 0 is secured in which amotor (Z for driving a fan al is mounted on a bracket (Z The front wall6 is formed at its bottom part with a large opening p.

In the operation of the apparatus air is taken in by the fan d anddelivered upwardly through the rear passage a and alongside the rearwall of the radiator. At the top of the casing the current of air isdirected downwardly and through the front passage (1 from which it isdelivered into the room through the opening )2. Thus air is transmittedinto the room by the current 9 of air and in addition by radiation.

In the modification shown in Figs. 3-5 the casing enclosing the radiatorconsists of a rear wall 0 and a front wall 6 and the rear wall 0 isprovided with a motor d and a fan ti the said motor and fan andassociated parts being similar in construction to the correspondingparts described with reference to Figs. 1 and 2. The front wall e isformed with an opening]? whlch extends from a part near the bottom to apart near the top of the casin The radiator comprises electrical heatingmembers 6 made in the form of wires helically wound on rods Ofrefractory material. Each heating element is disposed within asemieylindrical radiating shield f located at the rear there of, and allthe said shields are disposed one above the other so as to provide apartition within the casing 0. At their adjacent margins the shields arespaced from each other to provide downwardly directed passages g. In theoperation of the apparatus the air taken in by the fan (1 flows upwardlythrough the rear passage of the casing, and thereafter downwardly to thefront side thereof from whence it is delivered through the openin 12 Aportion of the air flowing upwar ly through the rear passage isdeflected through the passages g and towards the heating elements, thuseffectively cooling the same and transmitting the heat outwardly andinto the room. The concave portion of the shields f is directedoutwardly, so that the heat radiated from the heating elements is throwninto the room.
